The purpose of this rule is to limit VOC emissions from architectural
coatings. This rule specifies architectural coatings storage, cleanup,
and labeling requirements. This rule also specifies the test methods for
determining the VOC content, VOC emissions, metallic content, and acid
content.

2.0 Applicability

This rule is applicable to any person who supplies, sells, offers for
sale, applies, or solicits the application of any architectural coating,
or who manufactures any architectural coating for use within the District.

3.2 Architectural Coatings: coatings applied to stationary structures
and their appurtenances, to mobile homes, to pavements, or to curbs.

below-ground wood from decay or insect attack and which contain a wood
preservative chemical registered by the California Department of Food and
Agriculture.

soluble in carbon disulfide, which consist mainly of hydrocarbons, and
which are obtained from natural deposits or as residues from the distillation
of crude oils or of low grades of coal.

3.5 Bond Breakers: coatings applied between layers of concrete to prevent
the freshly poured top layer of concrete from bonding to the layer over
which it is poured.

3.9 Enamel Undercoaters: coatings which are designed to be applied to
a new surface over a primer or over a previous coat of paint in order to
improve the seal, provide better adhesion and make a smooth base for non-flat
coatings.

3.10 Exempt Compounds: compounds identified as exempt under the definition
of VOCs, in Rule 1020 (Definitions).

3.11 Fire Retardant Coatings: coatings which have a flame spread index

prevent the freshly poured concrete from bonding to the form. The form
may consist of wood, metal, or any material other than concrete.

3.13 Grams of VOC per Liter of Coating, Excluding Water and Exempt Compounds:
the weight of VOC per combined volume of VOC and coating solids, and is
calculated by the following equation:

Grams of VOC per Liter of Coating,

Excluding Water and Exempt Compounds =

Where:

Ws = weight of volatile compounds in grams

Ww = weight of water in grams

Wec = weight of exempt compounds in grams

Vm = volume of material in liters

Vw = volume of water in liters

Vec = volume of exempt compounds in liters

3.14 Grams of VOC per liter of Material: the weight of VOC per volume
of material, and is calculated by the following equation:

considered to be in this category, but shall be considered to be in the
metallic pigmented coatings category.

3.33 Sanding Sealers: clear wood coatings formulated for and applied
to bare wood to prepare it for sanding and to seal the wood for subsequent
application of varnish. To be considered a sanding sealer, a coating must
be clearly labeled as such.

prevent subsequent coatings from being absorbed by the substrate, or to
prevent harm to subsequent coatings by materials in the substrate.

of a surface but not conceal the surface.

3.36 Semi-Transparent Wood Preservatives: wood preservative stains formulated
and used to protect exposed wood from decay or insect attack by the addition
of a wood preservative chemical registered by the California Department
of Food and Agriculture, which change the color of a surface but do not
conceal the surface, including clear wood preservatives.

3.37 Shellacs: clear or pigmented coatings formulated solely with the
resinous secretions of the lac beetle (laccifer lacca), thinned with alcohol,
and formulated to dry by evaporation without a chemical reaction.

3.38 Solicit: to require for use or to specify, by written or oral contract.

3.39 Specialty Flat Products: self priming flat products used only to
perform one of the following functions: repair fire; smoke or water damage;

a tough, extra-durable coating system, which are applied as a continuous
(seamless) high build film and which cure to a hard glaze finish.

3.43 Traffic Coatings: coatings formulated for and applied to public
streets, highways, and other surfaces including, but not limited to curbs,
berms, driveways, and parking lots.

3.44 Undercoaters: coatings formulated and applied to substrates to
provide a smooth surface for subsequent coats.

3.45 Varnishes: clear wood finishes formulated with various resins to
dry by chemical reaction or exposure to air.

3.46 Waterproofing Mastic Coatings: weatherproof and waterproof coatings
which are formulated to cover holes and minor cracks and to conceal surface
irregularities, and which are to be applied in thickness of at least 15
mils.

3.47 Waterproofing Sealers: colorless coatings which are formulated
and applied for the sole purpose of protecting porous substrates by preventing

6.0 Administrative Requirements

6.1 Labeling Requirements:

6.1.1 Date of Manufacture: Each container of any coating subject to
this rule shall display the date on which the contents were manufactured
or a code indicating the date of manufacture. Each manufacturer of such

to this rule shall display a statement of the manufacturer's recommendation
regarding thinning of the coating. This requirement shall not apply to
the thinning of architectural coatings with water. The recommendation shall
specify that the coating is to be employed without thinning or diluting
under normal environmental and application conditions, unless the recommended
thinning for normal environmental and application conditions does not cause
a coating to exceed its applicable VOC standard.
